In the past moving from SM 9.3X to 9.4X (Hydrid) required first to install the Process Designer Content Pack and then upgrading to SM 9.4X. I see in the documentation that this requirement is no longer in place, but I want to be sure that this is actually possible and that I will have an SM 9.52 in Hybrid mode (not 9.52 Classic), with Process Designer available to be used.
Also what will happen with the current Change Categories that I have? Are they automatically migrated to PD? What happens to customizations done in the related Change processess, for instance to automatically move forward a change when some conditions happen?
